I've run a non-trivial business that depended on secrecy, and I recognize some of the ideas from the guy above. I wouldn't say "just let the government run this hedge fund", but there's some truth to what he's saying.

I think it's also important that people can make comments on large social issues such as corporate transparency without feeling like they need to be experts. In fact, nobody can be an expert on these sweeping issues, because these laws affect such a wide variety of entities.

I don't think the doctor comparison holds water. With a lot of work, someone can be recognized as a medical expert, but it's still a specific field that one can be qualified in.
